This datapack adds a thirst bar to the game and makes survival a bit harder because you have to keep yourself hydrated all the time. Your water decreases depending on your movement and your speed.

To refill the first bar, you can drink a water bottle or any potion, milk, mushroom stew, eat melon or stand in a block of water.

If your first bar becomes empty, you will be affected by nausea, hunger and mining fatigue.

How to install:

unzip the downloaded file and paste the "Thirst datapack" folder into .minecraft > saves > your_save > datapacks

if your game is already open, you will need to run /reload so the game registers the datapack.
